"It's a fun show. Everybody talks about how much hard work it is, and the rehearsals and the practices and the injuries and all that stuff. But they don't talk about how much fun it actually is to be a part of the show and the energy you get from the live performance. I mean, that's what I feed off of and that's why I want to come do it again," he said.

He also said he wouldn't mind claiming another trophy.

"My first trophy fell apart, it's crumbling as we speak, so I need another one to take its place," he said.

For Gilles Marini, the competition is all in good fun.

"The competition is going to be there no matter what, it's going to be amazing people that you have to actually compete with. I just want to push the competition a bit aside and perform for the people," he said.

Returning to the show is also something he couldn't pass up.

"It's great to have one shot and then get another one. In life, this is not something you get everyday," Marini said.
